While the Compensation Committee considers peer group analysis as a component of its overall executive compensation decision process, it does not engage in benchmarking executive compensation against a specific level, range or percentile of compensation paid by other companies. See “Executive Compensation” for additional information.

Nominating Committee

As a “controlled company”, Marshall Edwards isRelated Transactions.” Controlled companies are not subject to the Nasdaq rules requiring (i) Board of Director nominations to be selected, or recommended for the Board’s selection, by either a nominating committee comprised solely of independent directors or by a majority of the independent directors on the Board of Directors and (ii) each Nasdaq-listed company to have a formal written charter or resolutions by the Board of Directors addressing the nominating process. Accordingly, during the fiscal year ended June 30, 2011, Marshall Edwards did not have a separately established Nominating Committee. The Board of Directors does not believe that any marked efficiencies or enhancements would be achieved by the creation of a separate Nominating Committee.

The duties and responsibilities typically delegated to a nominating committee are included in the responsibilities of the entire Board of Directors. The Board of Directors identifies nominees by first evaluating the current members ofNominating Committee is responsible for assisting the Board of Directors willingin identifying qualified individuals who possess the desired experience and skills to continue in service.serve on the Board. The Nominating Committee is also responsible for proposing chairpersons and members on committees to the Board. If any member of the Board of Directors does not wish to continue in service or if the Board of Directors decides not to re-nominate a member for re-election, the Board will consider all qualified director candidates identified by members of the Board,Nominating Committee or by senior management and stockholders. Stockholders who would like to propose an independent director candidate for consideration for nomination by the Board of Directors at next year’s annual meeting of stockholders may do so by submitting the candidate’s name, resume and biographical information to the attention of Thomas M.

The Board of DirectorsNominating Committee reviews each directorthe prospective candidate’s biographical information and assesses each candidate’s independence, diversity, skills and expertise based on a variety of factors, including the following criteria:

Application of these factors requires the exercise of judgment by members of the Nominating Committee when it makes recommendations to the Board of Directors and cannot be measured in a quantitative way. In addition, the Nominating Committee considers, as one factor among many, the diversity of Board candidates, which may include diversity of skills and experience as well as geographic, gender, age, and ethnic diversity. The Nominating Committee does not, however, have a formal policy with regard to the consideration of diversity in identifying Board candidates. The Nominating Committee and the Board of Directors generally valuesvalue the broad business experience and independent business judgment in the health care, life sciences and other fields of each member. Specifically, with respect to Professor Williams, the Board relieshas relied on his experience in basic and pre-clinical cancer research. Ms. Cann is qualified for the Board based on her business experience in the health care field and her status as an

“audit “audit committee expert.” Dr. White is qualified for the Board based on her business and medical experience in the health care field, including oncology research. Mr. Rueckert is qualified for the Board based on his business experience in the investment industry. Mr. Baltic is qualified for the Board as a result of his business experience in the health care investment banking industry. Dr. Reynolds is qualified for the Board as a result of his business and medical experience in the health care field.

Governance Agreements

We have entered into separate governance agreements with two of the investors in our December 2012 private placement financing, Vivo Ventures Fund VII, L.P. (“Vivo”) and New Leaf Ventures II, L.P. (“New Leaf”), pursuant to which each of them is entitled to propose a candidate for election to our Board for consideration by the Nominating Committee in connection with each annual meeting of our stockholders following the effectiveness of an amended and restated certificate of incorporation eliminating our classified board of directors, and at such other times as such investor may propose. We have agreed to use our best efforts to cause the Board to elect one of the candidates proposed by Vivo or New Leaf to serve as Chairman of the Board and to cause the Board to appoint at least one of any such candidates serving on the Board to serve on each standing and special committee of the Board. All candidates proposed by Vivo and New Leaf will be presented to the Nominating Committee for the same consideration as individuals identified by the Nominating Committee through other means. Each governance agreement will terminate with respect to the applicable investor at the earliest of (i) such time as such investor and its affiliates beneficially owns all of the shares of common stock then outstanding, (ii) such time as such investor and its affiliates beneficially own less than 10% of the shares of common stock then outstanding, or (iii) the effectiveness of certain change of control transactions resulting in continuing stockholders of the Company holding less than 50% of the outstanding voting securities of the Company, its successor entity or a parent or subsidiary of its successor entity. Dr. Reynolds was proposed to the Nominating Committee pursuant to the terms of the governance agreements. Also, it is expected that at a future date, a candidate proposed under the governance agreements will be considered by the Nominating Committee to fill the vacancy on the Board that will be created upon Professor Williams’s retirement from the Board at the Annual Meeting.

Director Independence

Marshall Edwards’Our Board of Directors has determined the independence of each director in accordance with the elements of independence set forth in the Nasdaq listing standards. Based upon information solicited from each director, Marshall Edwards’our Board of Directors has determined that each of Mr. William Rueckert, Dr. Christine White, Professor Bryan Williams, Ms. Leah Cann, Mr. Baltic and Mr. Charles V. Baltic IIIDr. Reynolds have no material relationship with Marshall EdwardsMEI Pharma and are “independent” within the meaning of Nasdaq’s director independence standards as currently in effect. In making the foregoing determinations, the Board of Directors has considered both the objective tests set forth in the Nasdaq independence standards and subjective measures with respect to each director necessary to determine that no relationships exist that would interfere with the exercise of independent judgment by each such director in carrying out the responsibilities of a director. In the case of Mr. Rueckert, the Board’s subjective determination included consideration of his role as non-executive chairman of the board of directors of Novogen.Novogen through his resignation of such position on December 7, 2012. Dr. Daniel P. Gold, as President and Chief Executive Officer of Marshall Edwards,MEI Pharma, is not considered independent in accordance with Nasdaq’s requirements.

Board Leadership Structure

The Board of Directors does not have a policy addressing whether the same person should serve as both the Chief Executive Officer and Chairman of the Board or if the roles should be separate. Our Board believes that it should have the flexibility to make its determination based upon what it considers to be the appropriate leadership structure for the Company at the time. The Board believes that its current leadership structure, with Dr. Gold serving as President and Chief Executive Officer and Professor Williams serving as Chairman, with Dr. White to serve as Lead Director commencing upon Professor Williams’s retirement and until a successor Chairman is elected, is appropriate for the Company at this time. The Company is currently engaged in a search for a new director to fill the vacancy on the Board created by Professor Williams’s decision not to stand for re-election, which director may also be qualified to serve as Chairman of the Board.

Board Role in Risk Oversight

Risk is an integral part of the Board and Committee deliberations throughout the year. While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk management. In particular, the Audit Committee focuses on financial risk, including

internal controls, and receives financial risk assessment reports from management. Risks related to the compensation programs are reviewed by the Compensation Committee. The Board is advised by these committees of significant risks and management’s response via periodic updates.

Stockholder Communications with the Board of Directors

Marshall Edwards’MEI Pharma’s stockholders may communicate with the Board of Directors, including non-executive directors or officers, by sending written communications addressed to such person or persons in care of Marshall Edwards,MEI Pharma, Inc., 11975 El Camino Real, Suite 101, San Diego, California, 92130. All communications will be compiled by the Secretary and submitted to the addressee. If the Board of Directors modifies this process, the revised process will be posted on Marshall Edwards’our website.

White, Mr. Philip Johnston (through April 13, 2011) and Mr. William D. Rueckert (beginning April 13, 2011). All of the Compensation Committee members during the fiscal year ended June 30, 2011 were non-employee directors and not former officers.

Marshall Edwards’ boardThe Board is currently divided into three classes with respect to the term of office, with the terms of office of one class expiring each successive year. This classified board provision could discourage a third party from making a tender offer for Marshall Edwards’our shares or attempting to obtain control of Marshall Edwards.MEI Pharma. It could also delay stockholders who do not agree with the policies of the Board of Directors from removing a majority of the Board of Directors for two years. As described under “Approval of Amended and Restated Certificate of Incorporation (Proposal No. 3)”, the Board has recommended for approval by the stockholders at the Annual Meeting certain amendments to our Restated Certificate of Incorporation to, among other things, declassify the Board such that directors would be elected on an annual basis, commencing with the annual meeting for the Company’s 2014 fiscal year. If the Amended and Restated Certificate of Incorporation is adopted and approved by the stockholders, each of the Company’s directors whose terms would otherwise extend beyond the annual meeting of stockholders for fiscal year 2014 has agreed to resign as a director and, if recommended by our Nominating Committee and nominated by our Board, stand for re-election at the annual meeting for fiscal year 2014.

A director may resign at any time. The resignation is effective on Marshall Edwards’ receipt of notice. Any or all directors may be removed with or without cause by a resolution of stockholders entitled to vote to elect directors. Vacancies from resignation or removal or expansion of the size of the board may be filled by resolution of a majority of directors then in office or by a sole remaining director, and any director so appointed shall serve for the remainder of the full term of the class of directors in which the vacancy occurred. As a result of Professor Williams’s decision not to stand for reelection to the Board at the Annual Meeting, there will be one vacancy on the Board after the Annual Meeting, which the Company has commenced a search to fill.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

As discussed below, since beginning to directly compensate its executive officers with the appointment of Dr. Gold in April 2010, and the subsequent appointments of Mr. Zech in June 2010 and Dr. Mass in June 2011, we have instituted a compensation program based on subjective evaluation of an individual executive’s performance of his or her responsibilities and contribution to achieving our clinical, operational and financial objectives, including achievement of written goals and objectives. Although the same factors and compensation elements are applied to each of our named executive officers, the compensation of our Chief Executive Officer reflects his leadership role and critical decision-making responsibility and significant duties. The Compensation Committee has been delegated the authority to approve the compensation of executives, including that of our Chief Executive Officer. The discussion below focuses on the principles we applied in connection with approving compensation packages in the course of the recruitment of our current Chief Executive Officer, Chief Financial Officer, and Chief Medical Officer and which we anticipate applying in the future.

Objectives of Compensation ProgramPhilosophy

We recognizebelieve that our employees are a critical asset. Consequently, a key objective of our compensation program, including our executive compensation program, is to attract, retain and motivate qualified, talented and diverse professionals who are enthusiastic about our mission. We seek to achieve these goals by rewarding successfulthe performance by our executives and Marshall Edwards, while aligning the interest of our executives with those of our stockholders, by including long-term equity as a component of their compensation.

General

We view each component of executive compensation as related but distinct, and we review total compensation of our executive officers significantly impacts our ability to ensure thatachieve our overall compensation goals are met.corporate goals. We, have not historically engaged in competitive benchmarking. We do attempt to establish compensation,therefore, place considerable importance on the design and determine the appropriate level for each compensation component, at levels comparable to companies with which we compete and other companies who employ similarly skilled personnel, consistent with our recruiting and retention goals, our view of internal equity and consistency, our overall performance and other considerations we deem relevant. Except as described below, we have not adopted any formal or informal policies or guidelines for allocating compensation between long-term and current compensation, between cash and non-cash compensation or among different forms of non-cash compensation. Instead, the Compensation Committee, in consultation with and upon recommendationadministration of our Chief Executive Officer, approves what it believesexecutive officer compensation program. This program is intended to beenhance stockholder value by attracting, motivating and retaining qualified individuals to perform at the appropriate levelhighest levels and mix of the various compensation components primarily focused on the particular goals of applicable executivesto contribute to our growth and employees in a particular year. We seek to reward oursuccess. Our executive officers based on a number of factors, including our operating results, individual performance, prior-period compensation, and the achievement of individual and corporate goals focused on the development of new products. Our executiveofficer compensation program is designed to recognize those executivesprovide compensation opportunities that contributeare tied to the achievementindividual and corporate performance. Each executive officer’s compensation package is comprised of our business objectives, to reward those individuals fairly over time, to retain those individuals who continue to perform at or above the levels that we expectthree key elements: (i) base salary, (ii) performance-based cash incentives and to closely align the compensation of those individuals with our performance on both a short-term and long-term basis. While we have identified below the particular compensation objective each element(iii) equity-based compensation. These elements of executive compensation serves, we believe that each element of compensation,are intended to a greater or lesser extent, serves each ofalign the objectivesinterests of our executive compensation program. We provide our executives the opportunity to be rewarded through equity ownership if Marshall Edwards performs well over time, while maintaining base salaries at levels comparable with those paid by comparably-sized public companies in our geographic area.

In the future, we expect our Compensation Committee to continue to maintain policies and guidelines for executive compensation, which align our executive officers’ interestsofficers with those of our stockholders, by incentivizing and rewarding performance.

Our Board of Directors intends to perform, at least annually, a review of executive officers’ overall compensation packages including the grant of equity compensation, including vesting schedules,are also designed to determine whether they provide adequate incentives and motivation and whether they adequately compensate executive officers relative to the market. In evaluating the market for attracting and retaining qualified executives, the Board of Directors relies upon its collective experiencebe competitive in our industry and through independent sources, when available, compares our compensation plans to similar companies. In addition, the Compensation Committee considers recommendations from the Chief Executive Officer, who bases such recommendations, in part, on discussions with other members of management.industry. The Compensation Committee did not retain afrom time to time consults with compensation consultant for the fiscal year ended June 30, 2011.

Elements of Compensation

The primary elements ofconsultants, legal counsel and other advisors in designing our executive compensation program, are:

Base Salary. We fix in relation to our corporate goals. The Compensation Committee reviews and analyzes executive officer base compensation at a level that we believe, based on the collective industry experience ofprovided by other companies in our Board of Directors andindustry. The Compensation Committee best enables uswill consider, as part of its periodic compensation reviews, the extent to hire and retain individualswhich additional equity awards are appropriate in a competitive environment and reward individual performance accordingorder to satisfactory levels of contribution to our overall business goals. Base salary is used to recognizefurther align the experience, skills, knowledge and responsibilities required of all of our employees, including executives. When establishing base salaries, the Compensation Committee, together with the Chief Executive Officer, considers a variety of factors, including seniority, responsibility, tenure with Marshall Edwards, the ability to replace the individual, and relative pay among executives in the respective geography.

Incentive Cash Bonuses. Annual cash bonuses are discretionary in nature but are tied to the achievement of specific results. For the fiscal year ended June 30, 2011, we provided discretionary performance bonuses to employees, including executives, to recognize individual performance or the achievement of important business objectives, such as achievement of certain drug development milestones, as well as operational and financial performance. We do expect to consider awarding bonuses for eachinterests of our executive officers payable either in whole or in part, depending on the extent to which the employee’s actual performance contributed towards the overall results of the company. We expect our Chief Executive Officer to propose executive bonus allocations to the Compensation Committee, which has ultimate approval authority. In making judgments for each individual executive, the Board of Directors uses actual results, its own expertise, experience past practice and the individual’s responsibilities and contribution to our actual results for the year by reference to pre-established goals or targets. No one element of an individual’s performance of his responsibilities or the resulting contribution to our overall results has a material impact on the decision-making process with respect to that individual. In our employment agreements, we have agreed that Dr. Gold, Mr. Zech, and Dr. Mass may receive bonuses of up to 40%, 20% and 20%, respectively, of their base salary. For the fiscal year ended June 30, 2011, the Compensation Committee awarded incentive cash bonuses of $120,000 to Dr. Gold and $50,000 to Mr. Zech in recognition of meeting or exceeding individual performance goals and the achievement of specific business objectives.

Long-Term Incentive Program. We believe that long-term performance is achieved through an equity ownership culture that encourages performance by our executive officers through the use of stock and stock-based awards. We utilize stock options to ensure that our executive officers have a continuing stake in our long-term success. Because our executive officers are awarded stock options with an exercise price equal to or greater than the fair market valuethose of our common stock on the date of grant, the determination of which is discussed below, these options will have value to the executive officers only if the market price of our common stock

increases after the date of grant.

TO AMEND AND RESTATE THE MARSHALL EDWARDS INC. 2008 STOCK OMNIBUS EQUITY COMPENSATION PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK THAT MAY BE SUBJECT TO AWARDS UNDER THE PLAN BY 1,800,000 AND TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK THAT MAY BE SUBJECT TO AWARDS GRANTED TO ANY INDIVIDUAL DURING ANY CALENDAR YEAR BY 300,000 (PROPOSAL NO. 2)

Marshall Edwards’ 2008 Stock Omnibus Equity Compensation Plan, which we refer to as the “Equity Plan,” was initially adopted in 2008 as the “Marshall Edwards, Inc. 2008 Stock Omnibus Equity Compensation Plan.” Effective October 20, 2011, the Marshall Edwards Board of Directors has amended and restated the Equity Plan, subject to the approval of our stockholders, to (1) increase the number of our shares of common stock with respect to which grants may be made under the Equity Plan from 700,000 shares to 2,500,000 shares, all of which shares may be subject to incentive stock options (“ISOs”), (2) increase the number of our shares of common stock with respect to which grants may be made to any individual during any calendar year under the Equity Plan from 100,000 shares to 400,000 shares and (3) make certain other changes to clarify the meaning and operation of various provisions of the Equity Plan, conform the Equity Plan to recent regulatory developments, and update

the effective date of the amended and restated Equity Plan. The effectiveness of the amendments described in (3) above is not subject to stockholder approval and those amendments are effective as of October 20, 2011. If the stockholders do not approve the amendment and restatement of the Equity Plan at the Annual Meeting, the increase in the number of shares of common stock reserved and available for issuance under the Equity Plan from 700,000 shares to 2,500,000 shares will not be effective and the increase in the number of our shares of common stock with respect to which grants may be made to any individual during any calendar year under the Equity Plan from 100,000 shares to 400,000 shares will not be effective.

The Marshall Edwards Board of Directors believes that the number of shares of our common stock provided for under the Equity Plan and the limit on the number of shares permitted to be granted to any individual in any calendar year will not be sufficient in view of the refocusing of Marshall Edwards’ development and growth efforts and other strategic initiatives being undertaken by the company. The Marshall Edwards Board of Directors has concluded that Marshall Edwards’ ability to attract, retain and motivate top quality employees, officers, directors, advisors and consultants is material to its success, and would be enhanced by its continued ability to grant equity compensation under the Equity Plan and facilitate the grant of larger annual awards from time to time. Additionally, over the next several years, Marshall Edwards intends to engage in additional equity financings that may have the effect of diluting the value of awards previously made under the Equity Plan. Thus, the Marshall Edwards Board of Directors believes that the interests of Marshall Edwards and the interests of its stockholders will be advanced if employees, officers, directors, advisors and consultants can continue to be offered the opportunity to acquire or increase their proprietary interests in the company and that awards can be made to offset the effect of any capital-raising efforts. The Marshall Edwards Board of Directors, therefore, believes that the availability of more shares under the Equity Plan and the increase in the number of shares permitted to be granted to any individual in any calendar year will ensure that there will continue to be a sufficient number of shares with which to achieve the compensation strategy of Marshall Edwards.

The other proposed amendments are intended to limit, clarify, and update the Equity Plan in various respects. The proposed amendments also provide that it is our intention that, where applicable, awards conform to sections 162(m), 409A, 280G of the of the Internal Revenue Code of 1986, as amended (the “Code”), Rule 16b-3 under the Exchange Act, and the Dodd-Frank Act. Finally, the proposed amendments update the effective date of the amended and restated Equity Plan.

Stockholder approval is being sought (i) in order to meet the published listing requirements of the NASDAQ Capital Market, (ii) so that compensation attributable to grants under the Equity Plan may qualify for an exemption from the $1,000,000 deduction limit under section 162(m) of the Code (see discussion of “Material Federal Income Tax Consequences” below), and (iii) in order for ISOs to meet the requirements of the Code.

The Equity Plan, as amended and restated, is set forth in Annex A to this proxy statement, and the following description of the Equity Plan is only intended to be a summary of the key provisions of the Equity Plan as proposed to be amended by this proposal. Such summary is qualified in its entirety by the actual text of the Equity Plan to which reference is made.

Description of the Equity Plan as Proposed to be Amended and Restated

The purpose of the Equity Plan is to provide a means for us to attract, retain, motivate and reward present and prospective advisors, employees and non-employee directors by increasing their ownership interests in the company. Under the Equity Plan, individual awards may take the form of: (i) options to purchase shares of Marshall Edwards common stock, including ISOs, non-qualified stock options or both; (ii) SARs; (iii) restricted stock, consisting of shares of Marshall Islands stock that are subject to forfeiture based upon the failure to satisfy employment-related restrictions; (iv) deferred stock, representing the right to receive shares of Marshall Islands stock in the future; (v) bonus stock and awards in lieu of cash compensation; (vi) dividend equivalents, consisting of a right to receive cash, other awards or other property equal in value to dividends paid with respect to a specified number of shares of Marshall Edwards stock; or (vii) other awards, not otherwise provided for,

denominated or payable in, or the value of which is based in whole or in part upon the market or book value of, Marshall Edwards stock. Dividend Equivalents may be paid, distributed or accrued in connection with any award issued under the Equity Plan, whether or not vested. Awards granted under the Equity Plan are generally not assignable or transferable, except by the laws of descent and distribution, unless permitted by Marshall Edwards’ compensation committee.

If and to the extent options and SARs granted under the Equity Plan terminate, expire or are cancelled, forfeited, exchanged or surrendered without being exercised or if any stock awards stock units, or other stock-based awards are forfeited, terminated, or otherwise not paid in full, the shares subject to such grants will become available again for purposes of the Equity Plan. Shares of common stock surrendered in payment of the exercise price of an option, or withheld for payment of taxes, shall not be available for re-issuance under the Equity Plan. Upon the exercise of an option through a net exercise procedure, or upon the exercise of a SAR, both for purposes of calculating the number of shares remaining available for issuance under the Equity Plan and the number of shares remaining available for exercise under such option or SAR, the number of such shares shall be reduced by the gross number of shares for which the option or SAR is exercised and without regard to any cash settlement of a SAR. Except as provided with respect to cash settlement of SARs, to the extent that any grants are paid in cash and not in shares of common stock, any shares previously subject to such grants shall again be available for issuance or transfer under the Equity Plan and shall not count against the share limits for purposes of shares available under the Equity Plan.

The Equity Plan is generally administered by the compensation committee of the Marshall Edwards Board of Directors, except that Marshall Edwards Board of Directors will perform the committee’s functions under the Equity Plan for purposes of grants of awards to members of the committee, and, to the extent permitted under applicable law and regulation, may perform any other function of the committee as well. The compensation committee has the authority, among other things, to: (i) select the present or prospective advisors, employees and non-employee directors entitled to be granted awards under the Equity Plan; (ii) determine the types of awards, or combinations thereof, and whether such awards are to operate on a tandem basis or in conjunction with other awards; (iii) determine the number of shares of Marshall Edwards common stock or units or rights covered by an award; and (iv) determine the other terms and conditions of any award, including, without limitation, any restrictions or limitations on transfer, any vesting schedules or the acceleration thereof and any forfeiture provisions or waivers thereof. Whether and to what extent terms of awards under the Equity Plan will be standardized has not yet been determined. However, the exercise price at which shares of Marshall Edwards common stock may be purchased pursuant to the grant of stock options under the Equity Plan may not be less than 100% of the fair market value of the shares covered by such grant on the date of grant, measured at the closing market price of the common stock on such date. The compensation committee’s authority with respect to awards to employees who are not directors or executive officers may be delegated to our officers or managers, including our Chief Executive Officer. This delegation may be revoked at any time.

Marshall Edwards’ present and prospective directors, officers, employees, advisors and consultants and those of its subsidiaries and affiliates are eligible for awards under the Equity Plan. As of October 21, 2011, Marshall Edwards estimates that approximately 14 individuals were eligible to participate in the Equity Plan, including its three executive officers and five non-employee directors. Since the selection of participants and their awards are to be determined in the discretion of the compensation committee, such individuals and their awards are not presently determinable.

As noted above, the maximum number of shares of Marshall Edwards common stock with respect to which awards may be made under the Equity Plan, as proposed to be amended and restated, may not exceed 2,500,000 shares, all of which may be shares of common stock subject to ISOs.

As of October 21, 2011, 464,550 shares of Marshall Edwards common stock were subject to outstanding awards under the Equity Plan, and no shares of common stock had been issued pursuant to the exercise or settlement of any awards granted under the Equity Plan since its inception in 2008. Accordingly, as of such date, under the current Equity Plan 235,450 additional shares could be the subject of new awards and 464,550 shares

would remain to be issued in settlement or exercise of outstanding awards. Under the Equity Plan as proposed to be amended and restated, and assuming no new grants or settlements or exercises of awards before this proposal becomes effective, 2,035,450 additional shares could be the subject of new awards and 464,550 shares would remain to be issued in settlement or exercise of outstanding awards. The number and kind of shares of Marshall Edwards common stock provided for under the Equity Plan is subject to adjustment, as discussed below.

As noted above, the Equity Plan, as proposed to be amended and restated, also provides that, during any calendar year, no participant may be granted awards that may be settled by delivery of more than 400,000 shares of Marshall Edwards common stock, subject to adjustment.

In the event that our compensation committee determines that any recapitalization, forward or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or exchange of shares or other securities, stock dividend or other special, large and non-recurring dividend or distribution (whether in the form of cash, securities or other property), liquidation, dissolution, or other similar corporate transaction or event, affects our shares such that an adjustment is appropriate in order to prevent dilution or enlargement of the rights of participants under the Equity Plan, then the committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and kind of shares of stock reserved and available for awards under the Equity Plan, including shares reserved for ISOs; (ii) the number and kind of shares of stock specified in the annual per-participant limitations under the Equity Plan; (iii) the number and kind of shares of outstanding restricted stock or other outstanding awards in connection with which shares have been issued; (iv) the number and kind of shares that may be issued in respect of other outstanding awards; and (v) the exercise price, grant price or purchase price relating to any award (or, if deemed appropriate, the committee may make provision for a cash payment, including, without limitation, payment based upon the intrinsic (i.e., in-the-money) value, if any, with respect to any outstanding award). In addition, the compensation committee shall make appropriate adjustments in the terms and conditions of, and the criteria included in, awards (including, without limitation, cancellation of unexercised or outstanding awards, or substitution of awards using stock of a successor or other entity) in recognition of unusual or nonrecurring events (including, without limitation, events described in the preceding sentence and events constituting a change in control) affecting us or our financial statements, or in response to changes in applicable law, regulation, or accounting principles.

Except as otherwise provided in individual award agreements, all conditions and restrictions relating to the continued performance of services with respect to the exercisability or full enjoyment of an award will accelerate or otherwise lapse immediately prior to a “change in control” (as defined in the Equity Plan). Upon the consummation of any transaction whereby we become a wholly-owned subsidiary of any corporation, all options outstanding under the Equity Plan will terminate (after taking into account any accelerated vesting), with or without the payment of any consideration therefor, including, without limitation, payment of the intrinsic (i.e., in-the-money) value of such options, as determined by the committee, unless such other corporation continues or assumes the Equity Plan as it relates to options then outstanding (in which case such other corporation will be treated as us for all purposes under the Equity Plan, and, the compensation committee of such other corporation shall make appropriate adjustment in the number and kind of shares of stock subject thereto and the exercise price per share thereof to reflect consummation of such transaction). If the Equity Plan is not to be so assumed, we will notify the participant at least ten days in advance of the consummation of such transaction.

As to any award granted as a stock option or SAR, the Equity Plan includes a restriction providing that the compensation committee may not, without prior stockholder approval to the extent required under applicable law or regulation, subsequently reduce the exercise price or grant price relating to such award, or take such other actions as may be considered a “repricing” of such award within the meaning given to “repricing” in accordance with the applicable stock exchange in which such shares of company stock are registered, as in effect from time to time. Adjustments to the exercise price or number of shares of Marshall Edwards common stock subject to a stock option or SAR to reflect the effects of a stock split or other extraordinary corporate transaction will not constitute a “repricing.”

All awards under the Equity Plan are subject to the applicable provisions of the Marshall Edwards’ clawback or recoupment policy, as such policy may be in effect from time to time.

The Equity Plan may be amended, altered, suspended, discontinued or terminated by the Marshall Edwards Board of Directors without stockholder approval unless such approval is required by law or regulation, including, without limitation, under the rules of any stock exchange or automated quotation system on which Marshall Edwards’ common stock is then listed or quoted. The compensation committee may waive any conditions or amend, alter, suspend, discontinue or terminate any award under the Equity Plan. No such change to the Equity Plan or any award may, without the participant’s consent, materially impair the rights of the participant under an outstanding award except as provided in the Equity Plan or applicable award agreement.

Material Federal Income Tax Consequences

The following is a brief description of the federal income tax consequences generally arising with respect to awards that may be granted under the Equity Plan. This discussion is intended for the information of Marshall Edwards stockholders considering how to vote at the Marshall Edwards Annual Meeting and not as tax guidance to individuals who may participate in the Equity Plan. The summary does not address the effects of other federal taxes or taxes imposed under state, local or foreign laws.

The grant of an option or SAR will create no tax consequences for the participant or Marshall Edwards. A participant will not have taxable income upon exercising an ISO (except that the alternative minimum tax may apply), and Marshall Edwards will receive no tax deduction at that time. Upon exercising an option other than an ISO, the participant must generally recognize ordinary income equal to the difference between the exercise price and the fair market value of the freely transferable and non-forfeitable stock received. In each case, Marshall Edwards will generally be entitled to a tax deduction equal to the amount recognized as ordinary income by the participant.

A participant’s disposition of stock acquired upon the exercise of an option or SAR generally will result in capital gain or loss measured by the difference between the sale price and the participant’s tax basis in such stock (or the exercise price of the option in the case of stock acquired by exercise of an ISO and held for the applicable ISO holding periods). Generally, there will be no tax consequences to Marshall Edwards in connection with a disposition of stock acquired upon the exercise of an option or other award, except that Marshall Edwards will generally be entitled to a tax deduction (and the participant will recognize ordinary taxable income) if stock acquired upon exercise of an ISO is disposed of before the applicable ISO holding periods have been satisfied.

With respect to awards granted under the Equity Plan that may be settled either in cash or in stock or other property that is either not restricted as to transferability or not subject to a substantial risk of forfeiture, the participant generally must recognize ordinary income equal to the cash or fair market value of stock or other property received. Marshall Edwards will generally be entitled to a tax deduction for the same amount. With respect to awards involving stock or other property that is restricted as to transferability and subject to a substantial risk of forfeiture, the participant generally must recognize ordinary income equal to the fair market value of the stock or other property received at the first time the stock or other property becomes transferable or not subject to a substantial risk of forfeiture, whichever occurs earlier. Marshall Edwards will generally be entitled to a tax deduction in an amount equal to the ordinary income recognized by the participant. A participant may elect to be taxed at the time of receipt of the stock or other property rather than upon the lapse of restrictions on transferability or substantial risk of forfeiture, but if the participant subsequently forfeits such stock or property, the participant would not be entitled to any tax deduction, including capital loss, for the value of the stock or property on which the participant previously paid tax. Such election must be made and filed with the Internal Revenue Service within 30 days after the receipt of the stock or other property.

As discussed above, in certain cases the federal income tax deduction to which Marshall Edwards otherwise is entitled may be limited by application of section 162(m) of the Code, which generally disallows a publicly-held corporation’s tax deduction for compensation paid to its chief executive officer and certain of its other most

highly compensated executive officers in excess of $1,000,000 in any year; however, compensation that qualifies as “performance-based compensation” is excluded from the $1,000,000 deductibility cap. Marshall Edwards intends that options and SARs granted under the Equity Plan at the fair market value of its common stock on the date of grant will qualify as performance-based compensation. Stock units, performance units, stock awards, dividend equivalents and other awards granted under the Equity Plan will qualify as performance-based compensation only when Marshall Edwards’ Compensation Committee conditions such grants on the achievement of specified performance goals in accordance with the requirements of section 162(m) of the Code.

Under section 409A of the Code, an award under the Equity Plan may be taxable to the participant at 20 percentage points above ordinary federal income tax rates at the time the award becomes vested, plus interest and penalties, even if that is prior to the delivery of cash or stock in settlement of the award, if the award constitutes “deferred compensation” under section 409A of the Code and the requirements of section 409A of the Code are not satisfied.

The Equity Plan provides that Marshall Edwards has the right to require participants under the Equity Plan to pay it an amount necessary for it to satisfy its federal, state, local and foreign tax withholding obligations with respect to such awards. Marshall Edwards may withhold from other amounts payable to such individual an amount necessary to satisfy these obligations. Unless the Compensation Committee or its designee determines otherwise, a participant may satisfy this withholding obligation by having shares acquired pursuant to the award withheld.

VOTE REQUIRED FOR APPROVAL

The affirmative vote of the holders of a majority of the outstanding shares of common stock present in person or represented by proxy at the Annual Meeting and entitled to vote is required to approve the amended and restated Marshall Edwards, Inc. 2008 Stock Omnibus Compensation Plan.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE AMENDMENT AND RESTATEMENT OF THE MARSHALL EDWARDS, INC. 2008 STOCK OMNIBUS COMPENSATION PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK THAT MAY BE SUBJECT TO AWARDS UNDER THE PLAN BY 1,800,000 AND TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK THAT MAY BE SUBJECT TO AWARDS GRANTED TO ANY INDIVIDUAL DURING ANY CALENDAR YEAR BY 300,000.

RATIFICATION OF APPOINTMENT OF BDO USA LLP (PROPOSAL NO. 3)

Background

The Audit Committee has selected BDO USA, LLP (“BDO USA”) as independent registered public accounting firm to audit the financial statements of Marshall Edwards for the fiscal year ending June 30, 2012. The Board of Directors is submitting the appointment of BDO USA to the stockholders for ratification as a matter of good corporate practice.

Effective as of January 18, 2011, the Audit Committee engaged BDO USA as the independent registered public accounting firm to audit Marshall Edwards’ financial statements for the fiscal year ending June 30, 2011. The Audit Committee approved the appointment of BDO USA to replace BDO Audit (NSW-VIC) Pty Ltd (formerly BDO Kendalls Audit & Assurance (NSW-VIC) Pty Limited) (“BDO Audit”) who resigned concurrent with the appointment of BDO USA effective January 18, 2011.

BDO Audit served as Marshall Edwards’ independent auditor for the fiscal years ended June 30, 2010 and June 30, 2009.

Each of BDO USA and BDO Audit are Member Firms of BDO International. The engagement of BDO USA and the concurrent resignation of BDO Audit as Marshall Edwards’ independent auditor resulted from the effective relocation of Company management to the United States from Sydney, Australia. The report of BDO USA on Marshall Edwards’ balance sheet as of June 30, 2011 and the related statements of operations, stockholders’ equity and cash flows for the year ended June 30, 2011, and for the period from December 1, 2000 (inception) through June 30, 2011, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope or accounting principle. The report of BDO Audit on Marshall Edwards’ balance sheets as of June 30, 2010 and June 30, 2009 and the related statements of operations, stockholders’ equity and cash flows for each of the years in the three year period ended June 30, 2010, and for the period from December 1, 2000 (inception) through June 30, 2010, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal year ended June 30, 2011, there were no disagreements with BDO USA on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of BDO USA, would have caused BDO USA to make reference to the subject matter of the disagreement in connection with their report on Marshall Edwards’ balance sheet as of June 30, 2011 and the related statements of operations, stockholders’ equity and cash flows for the year ended June 30, 2011 and for the period from December 1, 2000 (inception) through June 30, 2011. During the fiscal year ended June 30, 2010, there were no disagreements with BDO Audit on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of BDO Audit, would have caused BDO Audit to make reference to the subject matter of the disagreement in connection with their report on Marshall Edwards’ balance sheets as of June 30, 2010 and June 30, 2009 and the related statements of operations, stockholders’ equity and cash flows for each of the years in the three year periods ended June 30, 2010, and for the period from December 1, 2000 (inception) through June 30, 2010.

During the fiscal years ended June 30, 2011 and June 30, 2010, there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

Prior to the engagement of BDO USA, neither Marshall Edwards nor anyone on behalf of Marshall Edwards consulted with BDO USA during the fiscal years ended June 30, 2011 and June 30, 2010 and the interim period

from July 1, 2010 through January 18, 2011, in any manner regarding either: (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on Marshall Edwards’ financial statements, and neither was a written report provided to Marshall Edwards nor was oral advice provided that BDO Audit concluded was an important factor considered by

Marshall Edwards in reaching a decision as to the accounting, auditing or financial reporting issue, or (b) a disagreement or a reportable event, as defined in Item 304(a)(1)(iv) and (v), respectively, of Regulation S-K.

Representatives of BDO USA are expected to be present at the Marshall Edwards Annual Meeting. The BDO USA representatives will have an opportunity to make a statement at the meeting and are expected to be available to respond to appropriate questions.

The ratification of the appointment of BDO USA, LLP as Marshall Edwards’ independent registered public accounting firm for the fiscal year ending June 30, 2012 will require approval by the majority of the votes cast by the holders of the shares of Marshall Edwards common stock voting in person or by proxy at the Annual Meeting. Stockholders may vote either for or against or abstain from voting on the proposal to ratify the selection of BDO USA, LLP as Marshall Edwards’ independent registered public accounting firm. Abstentions and broker non-votes, if any, will be counted for the purposes of determining the presence or absence of a quorum, but will have no effect on the ratification of BDO USA, LLP as Marshall Edwards’ independent registered public accounting firm for the fiscal year ending June 30, 2012. A failure to vote by not returning a signed proxy will have no effect on the outcome of the proposal.

In the event that the stockholders fail to ratify the appointment, the Audit Committee will reconsider its selection of audit firms, but may decide not to change its selection. Even if the appointment is ratified, the Audit Committee may appoint a different independent registered public accounting firm at any time if it determines that such a change would be in Marshall Edwards’ stockholders’ best interest.

THE AUDIT COMMITTEE AND THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMEND THAT THE STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF BDO USA, LLP TO ACT AS MARSHALL EDWARDS’ INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING JUNE 30, 2012.

APPROVAL OF AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

(PROPOSAL NO. 3)

On November 4, 2012, we entered into a Securities Purchase Agreement with Vivo Ventures Fund VII, L.P. and Vivo Ventures VII Affiliates Fund, L.P. (collectively, “Vivo”), New Leaf Ventures II, L.P. (“New Leaf”) and certain other accredited investors identified in Exhibit A thereto. Pursuant to the Securities Purchase Agreement, we agreed to use our best efforts to hold a meeting of stockholders within three months of the consummation of the transactions contemplated by the Securities Purchase Agreement to consider the approval of an Amended and Restated Certificate of Incorporation that, among other things, eliminates our classified Board of Directors, resulting in the annual election of directors, and alters certain existing provisions relating to corporate opportunities presented to stockholders of the Company. Accordingly, our Board of Directors has unanimously approved an amendment and restatement of our certificate of incorporation to declassify the Board, as well as to make certain other changes to the provisions relating to corporate opportunities, and recommends that the stockholders vote in favor of the Amended and Restated Certificate of Incorporation. In deliberating on the amendment, our Board of Directors considered the evolving standards of corporate governance and the concerns of our stockholders, as well as the benefits to the Company of the transactions contemplated by the Securities Purchase Agreement.

Classified boards have a long history of providing effective protection against coercive and/or inadequate takeovers and proxy contests that are not in the best interests of stockholders because they make it difficult for a substantial stockholder to gain control of a board without the cooperation or approval of incumbent directors. Classified boards also foster continuity and stability, not only on the board but also in the overall business of a company, since a majority of directors will always have prior experience as directors of the company. The Company’s current classified structure was adopted to take advantage of these perceived benefits. In recent years, however, there has been a growing sentiment among investors in favor of annual elections. This trend is based in part on the belief that classified boards may also reduce the accountability of directors to stockholders since stockholders are only able to evaluate and elect each director every three years. Moreover, many investors believe that the election of directors is the primary means for stockholders to influence corporate governance policies and to hold management accountable for implementing those policies.

In deciding to approve the Amended and Restated Certificate of Incorporation and to recommend the same for approval by the Company’s stockholders, the Board of Directors, assisted by the Nominating Committee, considered the arguments in favor of and against continuation of the classified Board of Directors, as well as the benefits to the Company of the transactions contemplated by the Securities Purchase Agreement, and determined that it is in the Company’s best interests to amend and restate the certificate of incorporation to eliminate the classified board of directors as proposed. In addition, the Board deemed it appropriate to modify the provisions of the certificate of incorporation relating to corporate opportunities to reflect that Novogen ceased to be the Company’s majority stockholder in December 2012.

Article Tenth of our Restated Certificate of Incorporation currently divides our Board of Directors into three classes of approximately equal size, composed of directors each serving terms of office of three years. Article Tenth would be deleted from the Amended and Restated Certificate of Incorporation as Delaware law provides that, unless otherwise provided in a company’s certificate of incorporation, directors are to be elected on an annual basis.

As described in “Certain Relationships and Related Party Transactions – Transactions and Corporate Opportunities”, Article Fourth of our current Restated Certificate of Incorporation defines and delineates the respective rights and duties of us, Novogen and some of our officers and directors relating to potential business opportunities that are the same as, or similar to, our business activities. While Novogen held at least 20% of our outstanding common stock, neither Novogen nor its officers, directors, affiliates or subsidiaries had any duty to refrain from pursuing, or liability for any breach of fiduciary duty by reason of pursuing, any of these opportunities. If approved, the Amended and Restated Certificate of Incorporation will provide that no

stockholder, nor any of its officers, directors, stockholders, affiliates, subsidiaries or employees, have a duty to refrain from pursuing, or liability for any breach of fiduciary duty as a stockholder by reason of pursuing, any of these opportunities, except where such opportunity is offered to certain of these individuals solely in their capacity as an officer or director of the Company. The Amended and Restated Certificate of Incorporation will also eliminate certain provisions that no longer apply as a result of Novogen’s ceasing to own a majority of our common stock, including certain indemnification obligations of the Company for liabilities arising out of actions against Novogen for any alleged breach of duty that was permitted under Article Fourth.

If the Amended and Restated Certificate of Incorporation is adopted and approved by the stockholders, each of the Company’s directors whose terms would otherwise extend beyond the annual meeting of stockholders for fiscal year 2014 has agreed to resign as a director and, if recommended by our Nominating Committee and nominated by our Board, stand for re-election at the annual meeting for fiscal year 2014.

If approved by the stockholders at the Annual Meeting, the proposed amendment and restatement of our certificate of incorporation will become effective upon the filing of the Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. We intend to file the Amended and Restated Certificate of Incorporation as soon as practicable after the Annual Meeting.

The full text of the proposed Amended and Restated Certificate of Incorporation is attached asAnnex A to this proxy statement, and is incorporated herein by reference. You are also encouraged to read the entire text of our current Restated Certificate of Incorporation, which was filed as Exhibit 3.1 to our Registration Statement on Form S-1 filed with the SEC on September 25, 2003.

VOTE REQUIRED

The approval of the Amended and Restated Certificate of Incorporation will require approval by eighty percent (80%) of the total number of votes eligible to be cast by the holders of all outstanding shares of MEI Pharma common stock. Stockholders may vote either for or against or abstain from voting on the proposal to amend and restated to the certificate of incorporation. Abstentions, broker non-votes and any failure to vote will have the effect of a vote “against” this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMEND THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION.

APPROVAL OF AMENDED AND RESTATED

2008 STOCK OMNIBUS EQUITY COMPENSATION PLAN

(PROPOSAL NO. 4)

MEI Pharma’s 2008 Stock Omnibus Equity Compensation Plan, which we refer to as the “Equity Plan,” was initially adopted in 2008 as the “MEI Pharma, Inc. 2008 Stock Omnibus Equity Compensation Plan” and subsequently amended and restated in 2011 to reflect an increase in the number of shares of common stock with respect to which grants could be made, both in the aggregate and to any individual. Effective January 30, 2013, the MEI Pharma Board of Directors has amended and restated the Equity Plan, subject to the approval of our stockholders, to (1) increase the number of our shares of common stock with respect to which grants may be made under the Equity Plan from 416,666 shares to 2,186,000 shares, all of which shares may be subject to incentive stock options (“ISOs”), (2) increase the number of our shares of common stock with respect to which grants may be made to any individual during any calendar year under the Equity Plan from 66,666 shares to 400,000 shares and (3) make certain other changes to clarify the meaning and operation of various provisions of the Equity Plan, conform the Equity Plan to recent regulatory developments, and update the effective date of the amended and restated Equity Plan.

The MEI Pharma Board of Directors believes that the number of shares of our common stock provided for under the Equity Plan and the limit on the number of shares permitted to be granted to any individual in any calendar year will not be sufficient in view of the substantial increase in the number of outstanding shares of common stock resulting from the Company’s December 2012 issuance of common stock and warrants to purchase common stock in a private placement transaction (the “December 2012 Private Placement”) and other strategic initiatives being undertaken by the Company. The Board of Directors has concluded that the Company’s ability to attract, retain and motivate top quality employees, officers, directors, advisors and consultants is material to its success, and would be enhanced by its continued ability to grant equity compensation under the Equity Plan and facilitate the grant of larger annual awards from time to time. Additionally, over the next several years, we may engage in additional equity financings that may have the effect of diluting the value of awards previously made under the Equity Plan. Thus, the Board of Directors believes that the interests of the Company and the interests of its stockholders will be advanced if employees, officers, directors, advisors and consultants can continue to be offered the opportunity to acquire or increase their proprietary interests in the company and that awards can be made to offset the effect of any capital-raising efforts. The Board of Directors, therefore, believes that the availability of more shares under the Equity Plan and the increase in the number of shares permitted to be granted to any individual in any calendar year will ensure that there will continue to be a sufficient number of shares with which to achieve our compensation strategy.

The other proposed amendments are intended to limit, clarify, and update the Equity Plan in various respects. The proposed amendments also provide that it is our intention that, where applicable, awards conform to sections 162(m), 409A, 280G of the of the Internal Revenue Code of 1986, as amended (the “Code”), Rule 16b-3 under the Exchange Act, and the Dodd-Frank Act. Finally, the proposed amendments update the effective date of the amended and restated Equity Plan.

We are seeking stockholder approval (i) in order to meet the published listing requirements of the NASDAQ Capital Market, (ii) so that compensation attributable to grants under the Equity Plan may qualify for an exemption from the $1,000,000 deduction limit under section 162(m) of the Code (see discussion of “Material Federal Income Tax Consequences” below), and (iii) in order for ISOs to meet the requirements of the Code.

The Equity Plan, as amended and restated, is set forth inAnnex B to this proxy statement, and the following description of the Equity Plan is only intended to be a summary of the key provisions of the Equity Plan as proposed to be amended by this proposal. Such summary is qualified in its entirety by the actual text of the Equity Plan to which reference is made.

Description of the Equity Plan as Proposed to be Amended and Restated

The purpose of the Equity Plan is to provide a means for us to attract, retain, motivate and reward present and prospective advisors, employees and non-employee directors by increasing their ownership interests in the company. Under the Equity Plan, individual awards may take the form of: (i) options to purchase shares of MEI Pharma common stock, including ISOs, non-qualified stock options or both; (ii) SARs; (iii) restricted stock, consisting of shares of MEI Pharma stock that are subject to forfeiture based upon the failure to satisfy employment-related restrictions; (iv) deferred stock, representing the right to receive shares of MEI Pharma stock in the future; (v) bonus stock and awards in lieu of cash compensation; (vi) dividend equivalents, consisting of a right to receive cash, other awards or other property equal in value to dividends paid with respect to a specified number of shares of MEI Pharma stock; or (vii) other awards, not otherwise provided for, denominated or payable in, or the value of which is based in whole or in part upon the market or book value of, MEI Pharma stock. Dividend Equivalents may be paid, distributed or accrued in connection with any award issued under the Equity Plan, whether or not vested. Awards granted under the Equity Plan are generally not assignable or transferable, except by the laws of descent and distribution, unless permitted by MEI Pharma’ compensation committee.

If and to the extent options and SARs granted under the Equity Plan terminate, expire or are cancelled, forfeited, exchanged or surrendered without being exercised or if any stock awards stock units, or other stock-based awards are forfeited, terminated, or otherwise not paid in full, the shares subject to such grants will become available again for purposes of the Equity Plan. Shares of common stock surrendered in payment of the exercise price of an option, or withheld for payment of taxes, shall not be available for re-issuance under the Equity Plan. Upon the exercise of an option through a net exercise procedure, or upon the exercise of a SAR, both for purposes of calculating the number of shares remaining available for issuance under the Equity Plan and the number of shares remaining available for exercise under such option or SAR, the number of such shares shall be reduced by the gross number of shares for which the option or SAR is exercised and without regard to any cash settlement of a SAR. Except as provided with respect to cash settlement of SARs, to the extent that any grants are paid in cash and not in shares of common stock, any shares previously subject to such grants shall again be available for issuance or transfer under the Equity Plan and shall not count against the share limits for purposes of shares available under the Equity Plan.

The Equity Plan is generally administered by the compensation committee of the Board of Directors, except that Board of Directors will perform the committee’s functions under the Equity Plan for purposes of grants of awards to members of the committee, and, to the extent permitted under applicable law and regulation, may perform any other function of the committee as well. The compensation committee has the authority, among other things, to: (i) select the present or prospective advisors, employees and non-employee directors entitled to be granted awards under the Equity Plan; (ii) determine the types of awards, or combinations thereof, and whether such awards are to operate on a tandem basis or in conjunction with other awards; (iii) determine the number of shares of MEI Pharma common stock or units or rights covered by an award; and (iv) determine the other terms and conditions of any award, including, without limitation, any restrictions or limitations on transfer, any vesting schedules or the acceleration thereof and any forfeiture provisions or waivers thereof. Whether and to what extent terms of awards under the Equity Plan will be standardized has not yet been determined. However, the exercise price at which shares of MEI Pharma common stock may be purchased pursuant to the grant of stock options under the Equity Plan may not be less than 100% of the fair market value of the shares covered by such grant on the date of grant, measured at the closing market price of the common stock on such date. The compensation committee’s authority with respect to awards to employees who are not directors or executive officers may be delegated to our officers or managers, including our Chief Executive Officer. This delegation may be revoked at any time.

MEI Pharma’ present and prospective directors, officers, employees, advisors and consultants and those of its subsidiaries and affiliates are eligible for awards under the Equity Plan. As of February 1, 2013, MEI Pharma estimates that approximately 17 individuals were eligible to participate in the Equity Plan, including its

three executive officers and five non-employee directors. Since the selection of participants and their awards are to be determined in the discretion of the Compensation Committee, such individuals and their awards are not presently determinable.

As noted above, the maximum number of shares of MEI Pharma common stock with respect to which awards may be made under the Equity Plan, as proposed to be amended and restated, may not exceed 416,666 shares, all of which may be shares of common stock subject to ISOs.

As of February 1, 2013, 225,726 shares of MEI Pharma common stock were subject to outstanding awards under the Equity Plan, and no shares of common stock had been issued pursuant to the exercise or settlement of any awards granted under the Equity Plan since its inception in 2008. Accordingly, as of such date, under the current Equity Plan, 190,940 additional shares could be the subject of new awards and 225,726 shares would remain to be issued in settlement or exercise of outstanding awards. Under the Equity Plan as proposed to be amended and restated, and assuming no new grants or settlements or exercises of awards before this proposal becomes effective, 1,769,334 additional shares could be the subject of new awards and 225,726 shares would remain to be issued in settlement or exercise of outstanding awards. The number and kind of shares of MEI Pharma common stock provided for under the Equity Plan is subject to adjustment, as discussed below.

As noted above, the Equity Plan, as proposed to be amended and restated, also provides that, during any calendar year, no participant may be granted awards that may be settled by delivery of more than 400,000 shares of MEI Pharma common stock, subject to adjustment.

In the event that our compensation committee determines that any recapitalization, forward or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or exchange of shares or other securities, stock dividend or other special, large and non-recurring dividend or distribution (whether in the form of cash, securities or other property), liquidation, dissolution, or other similar corporate transaction or event, affects our shares such that an adjustment is appropriate in order to prevent dilution or enlargement of the rights of participants under the Equity Plan, then the committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and kind of shares of stock reserved and available for awards under the Equity Plan, including shares reserved for ISOs; (ii) the number and kind of shares of stock specified in the annual per-participant limitations under the Equity Plan; (iii) the number and kind of shares of outstanding restricted stock or other outstanding awards in connection with which shares have been issued; (iv) the number and kind of shares that may be issued in respect of other outstanding awards; and (v) the exercise price, grant price or purchase price relating to any award (or, if deemed appropriate, the committee may make provision for a cash payment, including, without limitation, payment based upon the intrinsic (i.e., in-the-money) value, if any, with respect to any outstanding award). In addition, the compensation committee shall make appropriate adjustments in the terms and conditions of, and the criteria included in, awards (including, without limitation, cancellation of unexercised or outstanding awards, or substitution of awards using stock of a successor or other entity) in recognition of unusual or nonrecurring events (including, without limitation, events described in the preceding sentence and events constituting a change in control) affecting us or our financial statements, or in response to changes in applicable law, regulation, or accounting principles.

Except as otherwise provided in individual award agreements, all conditions and restrictions relating to the continued performance of services with respect to the exercisability or full enjoyment of an award will accelerate or otherwise lapse immediately prior to a “change in control” (as defined in the Equity Plan). Upon the consummation of any transaction whereby we become a wholly-owned subsidiary of any corporation, all options outstanding under the Equity Plan will terminate (after taking into account any accelerated vesting), with or without the payment of any consideration therefor, including, without limitation, payment of the intrinsic (i.e., in-the-money) value of such options, as determined by the committee, unless such other corporation continues or assumes the Equity Plan as it relates to options then outstanding (in which case such other corporation will be treated as us for all purposes under the Equity Plan, and, the compensation committee of such other corporation

shall make appropriate adjustment in the number and kind of shares of stock subject thereto and the exercise price per share thereof to reflect consummation of such transaction). If the Equity Plan is not to be so assumed, we will notify the participant at least ten days in advance of the consummation of such transaction.

As to any award granted as a stock option or SAR, the Equity Plan includes a restriction providing that the compensation committee may not, without prior stockholder approval to the extent required under applicable law or regulation, subsequently reduce the exercise price or grant price relating to such award, or take such other actions as may be considered a “repricing” of such award within the meaning given to “repricing” in accordance with the applicable stock exchange in which such shares of company stock are registered, as in effect from time to time. Adjustments to the exercise price or number of shares of MEI Pharma common stock subject to a stock option or SAR to reflect the effects of a stock split or other extraordinary corporate transaction will not constitute a “repricing.”

All awards under the Equity Plan are subject to the applicable provisions of the MEI Pharma’ clawback or recoupment policy, as such policy may be in effect from time to time.

The Equity Plan may be amended, altered, suspended, discontinued or terminated by the Board of Directors without stockholder approval unless such approval is required by law or regulation, including, without limitation, under the rules of any stock exchange or automated quotation system on which MEI Pharma’ common stock is then listed or quoted. The compensation committee may waive any conditions or amend, alter, suspend, discontinue or terminate any award under the Equity Plan. No such change to the Equity Plan or any award may, without the participant’s consent, materially impair the rights of the participant under an outstanding award except as provided in the Equity Plan or applicable award agreement.

Material Federal Income Tax Consequences

The following is a brief description of the federal income tax consequences generally arising with respect to awards that may be granted under the Equity Plan. This discussion is intended for the information of MEI Pharma stockholders considering how to vote at the MEI Pharma Annual Meeting and not as tax guidance to individuals who may participate in the Equity Plan. The summary does not address the effects of other federal taxes or taxes imposed under state, local or foreign laws.

The grant of an option or SAR will create no tax consequences for the participant or MEI Pharma. A participant will not have taxable income upon exercising an ISO (except that the alternative minimum tax may apply), and MEI Pharma will receive no tax deduction at that time. Upon exercising an option other than an ISO, the participant must generally recognize ordinary income equal to the difference between the exercise price and the fair market value of the freely transferable and non-forfeitable stock received. In each case, MEI Pharma will generally be entitled to a tax deduction equal to the amount recognized as ordinary income by the participant.

A participant’s disposition of stock acquired upon the exercise of an option or SAR generally will result in capital gain or loss measured by the difference between the sale price and the participant’s tax basis in such stock (or the exercise price of the option in the case of stock acquired by exercise of an ISO and held for the applicable ISO holding periods). Generally, there will be no tax consequences to MEI Pharma in connection with a disposition of stock acquired upon the exercise of an option or other award, except that MEI Pharma will generally be entitled to a tax deduction (and the participant will recognize ordinary taxable income) if stock acquired upon exercise of an ISO is disposed of before the applicable ISO holding periods have been satisfied.

With respect to awards granted under the Equity Plan that may be settled either in cash or in stock or other property that is either not restricted as to transferability or not subject to a substantial risk of forfeiture, the participant generally must recognize ordinary income equal to the cash or fair market value of stock or other property received. MEI Pharma will generally be entitled to a tax deduction for the same amount. With respect to awards involving stock or other property that is restricted as to transferability and subject to a substantial risk of forfeiture, the participant generally must recognize ordinary income equal to the fair market value of the stock or

other property received at the first time the stock or other property becomes transferable or not subject to a substantial risk of forfeiture, whichever occurs earlier. MEI Pharma will generally be entitled to a tax deduction in an amount equal to the ordinary income recognized by the participant. A participant may elect to be taxed at the time of receipt of the stock or other property rather than upon the lapse of restrictions on transferability or substantial risk of forfeiture, but if the participant subsequently forfeits such stock or property, the participant would not be entitled to any tax deduction, including capital loss, for the value of the stock or property on which the participant previously paid tax. Such election must be made and filed with the Internal Revenue Service within 30 days after the receipt of the stock or other property.

As discussed above, in certain cases the federal income tax deduction to which MEI Pharma otherwise is entitled may be limited by application of section 162(m) of the Code, which generally disallows a publicly-held corporation’s tax deduction for compensation paid to its chief executive officer and certain of its other most highly compensated executive officers in excess of $1,000,000 in any year; however, compensation that qualifies as “performance-based compensation” is excluded from the $1,000,000 deductibility cap. MEI Pharma intends that options and SARs granted under the Equity Plan at the fair market value of its common stock on the date of grant will qualify as performance-based compensation. Stock units, performance units, stock awards, dividend equivalents and other awards granted under the Equity Plan will qualify as performance-based compensation only when MEI Pharma’ Compensation Committee conditions such grants on the achievement of specified performance goals in accordance with the requirements of section 162(m) of the Code.

Under section 409A of the Code, an award under the Equity Plan may be taxable to the participant at 20 percentage points above ordinary federal income tax rates at the time the award becomes vested, plus interest and penalties, even if that is prior to the delivery of cash or stock in settlement of the award, if the award constitutes “deferred compensation” under section 409A of the Code and the requirements of section 409A of the Code are not satisfied.

The Equity Plan provides that MEI Pharma has the right to require participants under the Equity Plan to pay it an amount necessary for it to satisfy its federal, state, local and foreign tax withholding obligations with respect to such awards. MEI Pharma may withhold from other amounts payable to such individual an amount necessary to satisfy these obligations. Unless the Compensation Committee or its designee determines otherwise, a participant may satisfy this withholding obligation by having shares acquired pursuant to the award withheld.

VOTE REQUIRED

The affirmative vote of the holders of a majority of the outstanding shares of common stock present in person or represented by proxy at the Annual Meeting and entitled to vote is required to approve the amended and restated MEI Pharma, Inc. 2008 Stock Omnibus Compensation Plan.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE AMENDMENT AND RESTATEMENT OF THE MEI PHARMA, INC. 2008 STOCK OMNIBUS COMPENSATION PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK THAT MAY BE SUBJECT TO AWARDS UNDER THE PLAN BY 1,769,334 AND TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK THAT MAY BE SUBJECT TO AWARDS GRANTED TO ANY INDIVIDUAL DURING ANY CALENDAR YEAR BY 333,334.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

OurNovogen was our majority shareholder from our inception through December 3, 2012. On such date, Novogen completed the distribution of substantially all of its MEI Pharma common stock to its shareholders. Historically, we licensed from Novogen the rights to Novogen patents and applications for our lead isoflavone-based drug candidates, as well as other compounds. Additionally, Novogen historically provided research and development services and administrative and finance services to us under service agreements. The license agreements were terminated in May 2011 in conjunction with our purchase of a portfolio of isoflavone-related assets from Novogen, which we refer to as the “Isoflavone Transaction”. The service agreements were terminated in December 2010.

The agreements we have entered into with our former parent corporation, Novogen, are each summarized below. As Novogen iswas our parent corporation, each of our agreements with Novogen is considered a related party transaction. Our Code of Business Conduct and Ethics provides that our Audit Committee, which is composed of independent directors in accordance with both Nasdaq and SEC guidelines, review and approve all related party transactions. As such, each of these agreements were reviewed and approved by the majority of the members of our Audit Committee who did not have an interest in the transactions. We believe that each of our executed agreements with Novogen was on terms as favorable to us as we could have obtained from unaffiliated third parties. The following description isdescriptions below are only a summary of what we believe are the material provisions of the agreements.

Isoflavone Transaction; Termination of License Agreements

In May 2011, we purchased from Novogen and Novogen Research Pty Limited, a wholly owned subsidiary of Novogen, certain assets used in or generated under or in connection with the discovery, development, manufacture and marketing of intellectual property and products based on the field of isoflavonoid technology and on compounds known as isoflavones, including those related to the drug candidates Phenoxodiol, Triphendiol, NV 143NV-143 and NV-128 (the “Isoflavone-related Assets”). In exchange, we issued to Novogen 1,000 shares of its Series A Convertible Preferred Stock and assumed specified potential liabilities related to these assets. The foregoing transactions are referred to collectively herein as the “Isoflavone Transaction”. Each share of Series A Convertible Preferred Stock is convertible at any time and from time to time and without the payment of additional consideration by the holder thereof into 4,827In November 2012, we issued 804,500 shares of our common stock. In addition, if a Phase II clinical trial involving any of the Isoflavone-related Assets has achieved a statistically significant result (p=0.05 or less) or a first patient is enrolled in a Phase III clinical trial involving such technology, whichever is earlier, each sharestock to Novogen upon its conversion of the Series A Convertible Preferred Stock not already converted may thereafter be converted into 9,654 shares of our common stock.Stock.

Prior to the consummation of the Isoflavone Transaction, we had license agreements with Novogen for the use of some of the Isoflavone-related Assets in the development and commercialization of drugs for the treatment of cancer. These agreements, which were terminated upon consummation of the Isoflavone Transaction as described below, covered only applications of such assets for use in the treatment of cancer, excluding dermatological applications, and not all possible therapeutic indications. The Isoflavone-related Assets also include patent families which we had not previously licensed, and which may provide additional product candidate development opportunities.

Upon the consummation of the Isoflavone Transaction, each of the following agreements, along with any other agreements relating thereto, with respect to the Isoflavone-related Assets, was terminated:

MEPL paid $5,000,000Prior to Novogen in February 2004, which was the first lump sum license fee payment due under the terms ofits termination, the Phenoxodiol License Agreement. Also, MEPL paid $2,000,000 to Novogen in January 2005 and $4,000,000 in January 2006 which were the annual milestone license fee payments due under the Phenoxodiol License Agreement. MEPL paid a second lump sum license fee of $5,000,000 to Novogen in July 2006 following the raising of funds in a private placement closed on July 11, 2006 (the “July 2006 PIPE”). This license fee was due on the later of November 1, 2003 or such later date when the cumulative total of all funds received from debt or equity issuances and

revenue received from commercialization (income other than sales) and sales of Phenoxodiol products exceeded $50,000,000. Following the July 2006 PIPE, the funds received from equity issuances exceeded $50,000,000 which triggered this license fee payment.

The Phenoxodiol License Agreement alsoagreement provided that, untilfor additional future payments. Until the expiration of the exclusivity period ofas defined in the Phenoxodiol license MEPLagreement, the Company would have been obligated to pay Novogen 2.5% of all net sales and 25% of commercialization income. After the exclusivity period, of the license,Company would have been obligated to pay Novogen 1.5% of net sales were required to be paid to Novogen. The preconditions to such payments did not occur.sales.

In addition to the foregoing amounts, the Phenoxodiol License Agreement was amended in June 2006 and April 2007 to provide that

If this event did not occur before March 31, 2008, then this amount would become due. The amount of $1,000,000 was$3 million to be paid to Novogen on March 31, 2008 underat the termsearlier of this agreement;

Additionally, the Company would have become due.

In addition, the Triphendiol and NV-143 License Agreement provided that MEPL mustbeen obligated to pay Novogen royalties of 5% of all net sales and 25% of commercialization income forduring the term of the license.

The right to indemnification conferred herein shall include the right to be paid by the Corporation the expenses (including attorneys’ fees) incurred in defending any such action in advance of its final disposition (an “Advancement of Expenses”); provided, however, that if, but only if and then only to the extent, the DGCL requires, an Advancement of Expenses incurred by an indemnitee hereunder shall be made only upon delivery to the Corporation of an undertaking (an “Undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a “Final Adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Article FOURTH or otherwise. The rights to indemnification and to the Advancement of Expenses conferred herein shall be contract rights and, as such, shall inure to the benefit of the indemnitee’s successors, assigns, heirs, executors and administrators.

(ii) If a claim for indemnification under this Article FOURTH hereof is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, except in the case of a claim for an Advancement of Expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an Advancement of Expenses) it shall be a defense that, and (ii) any suit brought by the Corporation to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the Corporation shall be entitled to recover such expenses only upon a Final Adjudication that, the indemnitee has not met the applicable standard for indemnification, if any, set forth in the DGCL. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that

indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth herein or in the DGCL, nor an actual determination by the Corporation (including its directors, or a committee thereof, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an Advancement of Expenses hereunder, or brought by the Corporation to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such Advancement of Expenses, under this Article FOURTH or otherwise, shall be on the Corporation.

(iii) The rights to indemnification and to the Advancement of Expenses conferred in this Article FOURTH shall not be exclusive of any other right which any person may have or hereafter acquire by any statute, this Certificate of Incorporation, theCorporation’s By-Laws, or any agreement, vote of stockholders or disinterested directors or otherwise.

(e)(f) Notice to Holders. Any person purchasing or otherwise acquiring any interest in shares of the capital stock of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article FOURTH.

The foregoing right of indemnification shall in no way be deemed exclusive of any other rights of indemnification to which such officer or director may be entitled under any statute, this Certificate of Incorporation, the By-Laws of the Corporation or any agreement, vote of stockholders or disinterested directors or otherwise.

SEVENTH: No person who is or was a director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director unless, and only to the extent that such director is liable (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or any amendment thereto or successor provision thereto, or (iv) for any transaction from which the director derived an improper personal benefit. This article shall not eliminate or limit the liability or a director for any act or omission occurring prior to the date when this article becomes effective. No amendment to, repeal or adoption of any provision of this Certificate of Incorporation inconsistent with this article shall apply to or have any effect on the liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment, repeal, or adoption of an inconsistent provision.

EIGHTH: Any and all right, title, interest and claim in or to any dividends declared by the Corporation, whether in cash, stock or otherwise, which are unclaimed by the stockholder entitled thereto for a period of six (6) years after the close of business on the payment date, shall be and be deemed to be extinguished and abandoned, and such unclaimed dividends in the possession of the Corporation, its transfer agents or other agents or depositaries, shall at such time become the absolute property of the Corporation, free and clear of any and all claims of any persons whatsoever.

NINTH: Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on application in a summary way of the Corporation or of any creditor or stockholder thereof, or on the application of any receiver or receivers appointed for the Corporation under Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under Section 279 of Title 8 of the Delaware Code, order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner asthe saidsuch court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of the Corporation as a consequence of such compromise or arrangement,the saidsuch compromise or arrangement andthe saidsuch reorganization shall, if sanctioned by the court to whichthe saidsuch application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation.

Any action of the Compensation Committee with respect to the Plan shall be final, conclusive and binding on all Persons, including the Company, its Affiliates, Grantees, or any Person claiming any rights under the Plan from or through any Grantee, except to the extent the Compensation Committee may subsequently modify, or take further action not inconsistent with, its prior action. If not specified in the Plan, the time at which the Compensation Committee must or may make any determination shall be determined by the Compensation Committee, and any such determination may thereafter be modified by the Compensation Committee. The express grant of any specific power to the Compensation

Committee, and the taking of any action by the Compensation Committee, shall not be construed as limiting any power or authority of the Compensation Committee. The Compensation Committee may delegate to officers or managers of the Company or any Affiliate of the Company the authority, subject to such terms as the Compensation Committee shall determine, to perform such functions as the Compensation Committee may determine, to the extent permitted under applicable law.

(c)Limitation of Liability. Each member of the Compensation Committee shall be entitled to, in good faith, rely or act upon any report or other information furnished to him by any officer or other employee of the Company or any of its Affiliates, the Company’s independent certified public accountants or any executive compensation consultant, legal counsel or other professional retained by the Company to assist in the administration of the Plan. To the fullest extent permitted by applicable law, no member of the Compensation Committee, nor any officer or employee of the Company acting on behalf of the Compensation Committee, shall be personally liable for any action, determination or interpretation taken or made in good faith with respect to the Plan, and all members of the Compensation Committee and any officer or employee of the Company acting on its behalf shall, to the extent permitted by law, be fully indemnified and protected by the Company with respect to any such action, determination or interpretation.

Section 5.Options

The Compensation Committee may grant Options to an Employee, Advisor or member of the Board upon such terms as the Compensation Committee deems appropriate. The following provisions are applicable to Options:

(a)Number of Shares. The Compensation Committee shall determine the number of Shares that will be subject to each Grant of Options to an Employee, Advisor or member of the Board.

(b)Type of Option and Price.

(i) The Compensation Committee may grant ISOs or Nonqualified Stock Options or any combination of the two, all in accordance with the terms and conditions set forth herein. ISOs may be granted only to employees of the Company or its parent or subsidiary corporations, as defined in Code section 424. Nonqualified Options may be granted to Employees, Advisors or members of the Board.

(ii) The Exercise Price of Shares subject to an Option shall be determined by the Compensation Committee and may be equal to or greater than the Fair Market Value of a Share on the date the Option is granted. However, an ISO may not be granted to an Employee who, at the time of grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary corporation of the Company, as defined in Code section 424, unless the Exercise Price per Share is not less than 110% of the Fair Market Value of a Share on the date of grant.

(iii) Each ISO shall provide that, if the aggregate Fair Market Value of the Shares on the date of the grant with respect to which ISOs are exercisable for the first time by a Grantee during any calendar year, under the Plan or any other stock option plan of the Company or a parent or subsidiary of the Company, exceeds $100,000, then the Option, as to the excess, shall be treated as a Nonqualified Option.

(c) Option Term. The Compensation Committee shall determine the term of each Option. The term of any Option for shall not exceed five years from the date of grant.

(d)(c)Option Termination. Except as provided below, an Option may only be exercised while the Grantee is employed or engaged by the Company or any Affiliate as an Advisor, Employee or member of the Board. Unless otherwise determined by the Compensation Committee and set forth in a Grant Letter, Options shall terminate on the earliest of:

(i) the date on which the Grantee is no longer employed or engaged by the Company and any Affiliate on account of the Grantee’s termination for Cause. In addition, notwithstanding any other provisions of this

Section 5, if the Compensation Committee determines that the Grantee has engaged in conduct that constitutes Cause at any time while the Grantee is employed or engaged by the Company and any Affiliate or after the Grantee’s termination of employment or engagement, any Option held by the Grantee shall immediately terminate and the Grantee shall automatically forfeit all Shares underlying any exercised portion of an Option for which the Company has not yet delivered the Share certificates, upon refund by the Company of the Exercise Price paid by the Grantee for such Shares. Upon any exercise of an Option, the Company may withhold delivery of Share certificates pending resolution of an inquiry that could lead to a finding resulting in a forfeiture;

(ii) the 91st day following the date the Grantee is no longer employed or engaged by the Company and any Affiliate for any reason other than Cause, death, or Disability;provided,however, that in all cases the portion of any Option that is not vested on the date of termination of employment or engagement shall terminate immediately upon such termination;

(iii) the first anniversary of the date the Grantee’s employment or engagement by the Company and any Affiliate terminates on account of the Grantee’s death or Disability; provided,however, that the portion of any Option that is not vested on the date of such termination of employment or engagement shall terminate immediately upon such termination;

(iv) the fifth anniversary of the date of grant as set forth in the Grant Letter; and

(v) cancellation, termination or expiration of the Options pursuant to action taken by the Compensation Committee in accordance with Section 13.

For purposes of the Plan, employment or engagement by the Company and any Affiliate shall mean employment or service as an Employee, Advisor or member of the Board (so that, for purposes of exercising Options, a Grantee shall not be considered to have terminated his employment or engagement until the Grantee ceases to be an Employee, Advisor and member of the Board), unless the Compensation Committee determines otherwise.

(e)(d)Exercise of Options. Only the vested portion of any Option may be exercised. A Grantee may exercise an Option that has become exercisable, in whole or in part, by delivering a notice of exercise to the Company. The Grantee shall pay the Exercise Price for an Option as specified by the Compensation Committee (i) in cash, (ii) unless the Compensation Committee determines otherwise, by delivering Shares owned by the Grantee and having a Fair Market Value on the date of exercise at least equal to the Exercise Price or by attestation (on a form prescribed by the Compensation Committee) to ownership of Shares having a Fair Market Value on the date of exercise at least equal to the Exercise Price, (iii) by payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, or (iv) by such other method as the Compensation Committee may approve. In addition, in the event the Compensation Committee so determines, to the extent an Option is at the time exercisable for vested shares of Company Stock, all or any part of that vested portion may be surrendered to the Company for an appreciation distribution payable in Shares with a Fair Market Value at the time of the Option surrender equal to the dollar amount by which the then Fair Market Value of the Shares subject to the surrendered portion exceeds the aggregate Exercise Price payable for those Shares. Shares used to exercise an Option shall have been held by the Grantee for the requisite period of time necessary to avoid adverse accounting consequences to the Company with respect to the Option. Payment for the Shares to be issued or transferred pursuant to the Option, and any required withholding taxes, must be received by the Company by the time specified by the Compensation Committee depending on the type of payment being made, but in all cases prior to the issuance or transfer of such Shares.

(f)(e)Grants to Non-Exempt Employees. Notwithstanding the foregoing, Options granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, may not be exercisable for at least six months after the date of grant (except that such Options may become exercisable, as determined by the Compensation Committee, upon the Grantee’s death, Disability or retirement, or upon a Change in Control or other circumstances permitted by applicable regulations).

(a)General Requirements. Shares issued or transferred pursuant to Stock Awards may be issued or transferred for consideration or for no consideration, and subject to restrictions or no restrictions, as determined

by the Compensation Committee. The Compensation Committee may, but shall not be required to, establish conditions under which restrictions on Stock Awards shall lapse over a period of time or according to such other criteria as the Compensation Committee deems appropriate, including, without limitation, restrictions based upon the achievement of specific performance goals. The period of time during which the Stock Awards will remain subject to restrictions will be designated in the Grant Letter as the “Restriction Period.”

(b)Number of Shares. The Compensation Committee shall determine the number of Shares to be issued or transferred pursuant to a Stock Award and the restrictions applicable to such Shares.

(c)Requirement of Employment or Service. If the Grantee is no longer employed or engaged by the Company or any Affiliate during a period designated in the Grant Letter as the Restriction Period, or if other specified conditions are not met, the Stock Award shall terminate as to all Shares covered by the Grant as to which the restrictions have not lapsed, and those Shares must be immediately returned to the Company. The Compensation Committee may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.

(d)Restrictions on Transfer and Legend on Stock Certificate. During the Restriction Period, a Grantee may not sell, assign, transfer, pledge or otherwise dispose of the Shares of a Stock Award except under Section 14(b) below. Unless otherwise determined by the Compensation Committee, the Company will retain possession of certificates for Shares of Stock Awards until all restrictions on such Shares have lapsed. Each certificate for a Stock Award, unless held by the Company, shall contain a legend giving appropriate notice of the restrictions in the Grant. The Grantee shall be entitled to have the legend removed from the stock certificate covering the Shares subject to restrictions when all restrictions on such Shares have lapsed. The Compensation Committee may determine that the Company will not issue certificates for Stock Awards until all restrictions on such Shares have lapsed.

(e)Right to Vote and to Receive Dividends. Unless the Compensation Committee determines otherwise, during the Restriction Period, the Grantee shall have the right to vote Shares of Stock Awards and to receive any dividends or other distributions paid on such Shares, subject to any restrictions deemed appropriate by the Compensation Committee, including, without limitation, the achievement of specific performance goals.

(f)Lapse of Restrictions.

The Compensation Committee may grant Stock Units, each of which shall represent one hypothetical Share, to an Employee, Advisor or member of the Board, upon such terms and conditions as the Compensation Committee deems appropriate. The following provisions are applicable to Stock Units:

(a)Crediting of Units. Each Stock Unit shall represent the right of the Grantee to receive a Share or an amount of cash based on the value of a Share, if and when specified conditions are met. All Stock Units shall be credited to bookkeeping accounts established on the Company’s records for purposes of the Plan.

(b)Terms of Stock Units. The Compensation Committee may grant Stock Units that are payable if specified performance goals or other conditions are met, or under other circumstances. Stock Units may be paid at the end of a specified performance period or other period, or payment may be deferred to a date authorized by the Compensation Committee. The Compensation Committee shall determine the number of Stock Units to be granted and the requirements applicable to such Stock Units.

(c)Requirement of Employment or Service. If the Grantee is no longer employed or engaged by the Company or any Affiliate prior to the vesting ofvestingof Stock Units, or if other conditions established by the Compensation Committee are not met, the Grantee’s Stock Units shall be forfeited. The Compensation Committee may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.

(d)Payment With Respect to Stock Units. Payments with respect to Stock Units shall be made in cash, Shares or any combination of the foregoing, as the Compensation Committee shall determine.

Section 8.Stock Appreciation Rights

The following provisions are applicable to SARs:

(a)General Requirements. The Compensation Committee may grant SARs to an Employee, Advisor or member of the Board separately or in tandem with any Option (for all or a portion of the applicable Option). Tandem SARs may be granted either at the time the Option is granted or at any time thereafter while the Option remains outstanding;provided,however, that, in the case of an ISO, SARs may be granted only at the time of the grant of the ISO. The Compensation Committee shall establish the base amount of the SAR at the time the SAR is granted.granted, which shall be equal to or greater than the Fair Market Value of a Share as of the date of grant of the SAR. The base amount of each SAR shall be equal to the per Share Exercise Price of the related Option, provided such Exercise Price is equal to or greater than the Fair Market Value of a Share as of the date of grant of the SAR or, if there is no related Option, an amount equal to or greater than the Fair Market Value of a Share as of the date ofGrantgrant of the SAR.

(b)Tandem SARs. In the case of tandem SARs, the number of SARs granted to a Grantee that shall be exercisable during a specified period shall not exceed the number of Shares that the Grantee may purchase upon the exercise of the related Option during such period. Upon the exercise of an Option, the SARs relating to the Shares covered by such Option shall terminate. Upon the exercise of SARs, the related Option shall terminate to the extent of an equal number of Shares.

(c)Exercisability. A SAR shall be exercisable during the period specified by the Compensation Committee in the Grant Letter and shall be subject to such vesting and other restrictions as may be specified in the Grant Letter. The Compensation Committee may accelerate the exercisability of any or all outstanding SARs at any time for any reason. SARs may only be exercised while the Grantee is employedisemployed or engaged by the Company or Affiliate or during the applicable period after termination of employment or engagement as described in Section 5(c) above. A tandem SAR shall be exercisable only during the period when the Option to which it is related is also exercisable.

(d)Grants to Non-Exempt Employees. Notwithstanding the foregoing, SARs granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, may not be exercisable for at least six months after the date of grant (except that such SARs may become exercisable, as determined by the Compensation Committee, upon the Grantee’s death, Disability or retirement, or upon a Change in Control or other circumstances permitted by applicable regulations).

(e)Value of SARs. When a Grantee exercises SARs, the Grantee shall receive in settlement of such SARs an amount equal to the value of the stock appreciation for the number of SARs exercised. The stock appreciation for a SAR is the amount by which the Fair Market Value of the underlying Share on the date of exercise of the SAR exceeds the base amount of the SAR as described in subsection (a) above.

(f)Form of Payment. The appreciation in a SAR shall be paid in Shares, cash or any combination of the foregoing, as the Compensation Committee shall determine. For purposes of calculating the number of Shares to be received, Shares shall be valued at their Fair Market Value on the date of exercise of the SAR.

Section 9.Other Stock-Based Awards

The Compensation Committee may grant Other Stock-Based Awards, which are awards (other than those described in Sections 5, 6, 7 and 8 of the Plan) that are based on or measured by Shares, to any Employee,

Advisor or member of the Board, on such terms and conditions as the Compensation Committee shall determine. Other Stock-Based Awards may be awarded subject to the achievement of performance goals or other conditions and may be payable in cash, Company Stock or any combination of the foregoing, as the Compensation Committee shall determine.

The following provisions shall apply to Grants of Stock Awards, Stock Units, Other Stock-Based Awards and Dividend Equivalents that are to be considered “qualified performance-based compensation” under Code section 162(m):

(a)Performance Goals.

(i) When Stock Awards, Stock Units, Other Stock-Based Awards or Dividend Equivalents that are to be considered “qualified performance-based compensation” are granted, the Compensation Committee shall establish in writing (i) the objective performance goals that must be met, (ii) the performance period during which the performance will be measured, (iii) the threshold, target and maximum amounts that may be paid if the performance goals are met, and (iv) any other conditions that the Compensation Committee deems appropriate and consistent with the Plan and Code section 162(m).

(ii) The business criteria may relate to the Grantee’s business unit or the performance of the Company and its parents and subsidiaries as a whole, or any combination of the foregoing. The Compensation Committee shall use objectively determinable performance goals based on one or more of the following criteria: stock price, earnings per share, net earnings, operating earnings, earnings before income taxes, EBITDA (earnings before income tax expense, interest expense, and depreciation and amortization expense), return on assets, shareholder return, return on equity, growth in assets, unit volume, sales or market share, or strategic business criteria consisting of one or more objectives based on meeting specified revenue goals, market penetration goals, geographic business expansion goals, cost targets or goals relating to acquisitions or divestitures.

(b)Establishment of Goals. The Compensation Committee shall establish the performance goals in writing either before the beginning of the performance period or during a period ending no later than the earlier of (i) 90 days after the beginning of the performance period or (ii) the date on which 25% of the performance period has been completed, or such other date as may be required or permitted under applicable regulations under Code section 162(m). The performance goals shall satisfy the requirements for “qualified performance-based compensation,” including the requirement that the achievement of the goals be substantially uncertain at the time they are established and that the goals be established in such a way that a third party with knowledge of the

relevant facts could determine whether and to what extent the performance goals have been met. The Compensation Committee shall not have discretion to increase the amount of compensation that is payable upon achievement of the designated performance goals.

(c)Announcement of Grants. The Compensation Committee shall certify and announce the results for each performance period to all Grantees after the announcement of the Company’s financial results for the performance period. If and to the extent that the Compensation Committee does not certify that the performance

goals have been met, the grants of Stock Awards, Stock Units, Other Stock-Based Awards and Dividend Equivalents for the performance period shall be forfeited or shall not be made, as applicable. If Dividend Equivalents are granted as “qualified performance-based compensation” under Code section 162(m), a Grantee may not accrue more than $1,000,000 of such Dividend Equivalents during any calendar year.

(d)Death, Disability or Other Circumstances. The Compensation Committee may provide that Stock Awards, Stock Units, Other Stock-Based Awards and Dividend Equivalents shall be payable or restrictions on such Grants shall lapse, in whole or in part, in the event of the Grantee’s death or Disability during the performance period, or under other circumstances consistent with the Treasury regulations and rulings under Code section 162(m).

Section 12.Deferrals

The Compensation Committee may permit or require a Grantee to defer receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Grantee in connection with any Stock Units or Other Stock-Based Awards. If any such deferral election is permitted or required, the Compensation Committee shall establish rules and procedures for such deferrals and may provide for interest or other earnings to be paid on such deferrals. The rules and procedures for any such deferrals shall be consistent with applicable requirements of Code section 409A.

Section 13.Adjustment Upon Changes in Capitalization.

In addition, the Compensation Committee shall make such adjustments as are appropriate in the terms and conditions of, and the criteria included in, Grants (including, without limitation, cancellation of Grants in exchange for the in-the-money value, if any, of the vested portion thereof, cancellation of unvested Grants for no consideration, cancellation of out-of-the-money Grants for no consideration, substitution of Grants using securities of a successor or other entity, acceleration of the time that Grants expire, or adjustment of performance targets) in recognition of unusual or nonrecurring events (including, without limitation, a Change in Control or an event described in the preceding sentence) affecting the Company or any Affiliate of the Company or the financial statements of the Company or any Affiliate of the Company, or in response to changes in applicable laws, regulations or accounting principles. Any adjustments to outstanding Grants shall be consistent with Code section 409A or 424, to the extent applicable. Any adjustments determined by the Compensation Committee shall be final, binding and conclusive.

Section 14.Restrictions on Shares.

(a)Restrictions on Issuing Shares. No Shares shall be issued or transferred under the Plan unless and until all applicable legal requirements have been complied with to the satisfaction of the Compensation Committee.

The Compensation Committee shall have the right to condition any Grant on the Grantee’s undertaking in writing to comply with such restrictions on any subsequent disposition of the Shares issued or transferred thereunder as the Compensation Committee shall deem necessary or advisable as a result of any applicable law, regulation or official interpretation thereof.

(b)Transfer Restrictions.

(i)Nontransferability of Options. Except as provided below, only the Grantee may exercise rights under a Grant during the Grantee’s lifetime. A Grantee may not transfer those rights except (A) by will or by the

laws of descent and distribution or (B) with respect to Grants other than ISOs, pursuant to a domestic relations order. When a Grantee dies, the personal representative or other Person entitled to succeed to the rights of the Grantee may exercise such rights. Any such successor must furnish proof satisfactory to the Company of his or her right to receive the Grant under the Grantee’s will or under the applicable laws of descent and distribution.

(ii)Transfer of Nonqualified Stock Options. Notwithstanding (i) above, the Compensation Committee may provide, in a Grant Letter, that a Grantee may transfer Nonqualified Options to family members, or one or more trusts or other entities for the benefit of or owned by family members, consistent with the applicable securities laws, according to such terms as the Compensation Committee may determine; provided that the Grantee receives no consideration for the transfer of the Nonqualified Option and the transferred Nonqualified Option shall continue to be subject to the same terms and conditions as were applicable to the Nonqualified Option immediately before the transfer.

(c)ISO Notice. A Grantee shall notify the Company of any disposition of Shares acquired upon exercise of an ISO if such disposition occurs within one year of the date of such exercise or within two years of the date of grant of such ISO. The Company may impose such procedures as it determines may be necessary to ensure that such notification is made.

(d)Requirements for Issuance or Transfer of Shares. No Shares shall be issued or transferred in connection with any Grant made hereunder unless and until all legal requirements applicable to the issuance or transfer of such Shares have been complied with to the satisfaction of the Compensation Committee. The Compensation Committee shall have the right to condition any Grant on the Grantee’s undertaking in writing to comply with such restrictions on his or her subsequent disposition of the Shares as the Compensation Committee shall deem necessary or advisable, and certificates representing such Shares may be legended to reflect any such restrictions. Certificates representing Shares issued or transferred under the Plan may be subject to such stop-transfer orders and other restrictions as the Compensation Committee deems appropriate to comply with applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.

Section 15.Withholding of Taxes.

All Grants made under the Plan shall be subject to applicable federal (including FICA), state and local tax withholding requirements. The Company may require that the Grantee or other Person receiving or exercising Grants pay to the Company or any Affiliate the amount of any federal, state or local taxes that the Company or any Affiliate is required to withhold with respect to such Grants, or the Company or any Affiliate may deduct from other wages paid by the Company or any Affiliate the amount of any withholding taxes due with respect to such Grants. If the Compensation Committee so permits, a Grantee may elect to satisfy the applicable tax withholding obligation with respect to a Grant by having Shares withheld up to an amount that does not exceed the Grantee’s minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities. The election must be in a form and manner prescribed by the Compensation Committee and may be subject to the prior approval of the Compensation Committee.

Section 16.Consequences of a Change in Control.

(a)Notice and Acceleration. Unless the Compensation Committee determines otherwise, effective upon the date of the Change in Control, (i) all outstanding Options and SARs shall automatically accelerate and become

fully exercisable, (ii) the restrictions and conditions on all outstanding Stock Awards shall immediately lapse, and (iii) all Stock Units, Other Stock-Based Awards and Dividend Equivalents shall become fully vested and shall be paid at their target values, or in such greater amounts as the Compensation Committee may determine.

(b)Other Alternatives. Notwithstanding the foregoing, in the event of a Change in Control, in addition to the actions described in Section 13, the Compensation Committee may take one or more of the following actions with respect to any or all outstanding Grants: the Compensation Committee may (i) require that Grantees

surrender their outstanding vested Options and SARs in exchange for one or more payments by the Company, in cash or Shares as determined by the Compensation Committee, in an amount equal to the amount by which the then Fair Market Value of the Shares subject to the Grantee’s unexercised, vested Options and SARs exceeds the Exercise Price of the vested Options or the base amount of the vested SARs, as applicable, (ii) provide for the cancellation of unvested Grants for no consideration, (iii) provide for the cancellation of out-of-the-money Grants for no consideration, (iv) after giving Grantees an opportunity to exercise their outstanding Options and SARs, terminate any or all unexercised Options and SARs at such time as the Compensation Committee deems appropriate, or (v) determine that outstanding Options and SARs that are not exercised shall be assumed by, or replaced with comparable options or rights by, the surviving corporation, (or a parent or subsidiary of the surviving corporation), and other outstanding Grants that remain in effect after the Change in Control shall be converted to similar grants of the surviving corporation (or a parent or subsidiary of the surviving corporation). Such surrender or termination shall take place as of the date of the Change in Control or such other date as the Compensation Committee may specify.

Section 17.General Provisions

(a)Grant Letter. Each Grant shall be evidenced by a Grant Letter. The terms and provisions of such Grant Letters may vary among Grantees and among different Grants made to the same Grantee.

(b)No Right to Employment. The making of a Grant in any year shall not give the Grantee any right to similar grants in future years, any right to continue such Grantee’s employment relationship with the Company or its Affiliates, or, until Shares are issued, any rights as a stockholder of the Company. All Grantees shall remain subject to discharge to the same extent as if the Plan were not in effect. For purposes of the Plan, a sale of any Affiliate of the Company that employs or engages a Grantee shall be treated as the termination of such Grantee’s employment or engagement, unless the Grantee shall otherwise continue to provide services to the Company or another subsidiary of the Company as an employee or director.

(c)No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Grant. Except as otherwise provided under the Plan, the Compensation Committee shall determine whether cash, other awards or other property shall be issued or paid in lieu of such fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated.

(d)No Funding. No Grantee, and no beneficiary or other Persons claiming under or through the Grantee, shall have any right, title or interest by reason of any Option to any particular assets of the Company or Affiliates of the Company, or any Shares allocated or reserved for the purposes of the Plan or subject to any Grant except as set forth herein. The Company shall not be required to establish any fund or make any other segregation of assets to assure satisfaction of the Company’s obligations under the Plan.

(e)Governing Law; Jurisdiction. The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. To the extent the Grantee is a party to an employment agreement with the Company or any of its subsidiaries that provides for binding arbitration of employment disputes, then any disputes between the Company and such Grantee arising under the Plan shall be arbitrated in accordance with the procedures set forth in such employment agreement.

(f)Compliance with Law. The Plan, the exercise of Options and SARs and the obligations of the Company to issue or transfer Shares under Grants shall be subject to all applicable laws and regulations, and to approvals by any governmental or regulatory agency as may be required. With respect to Persons subject to section 16 of the Exchange Act, it is the intent of the Company that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. In addition, it is the intent of the Company that ISOs comply with the applicable provisions of Code section 422, that the Plan comply with the

applicable provisions of Code section 162(m) and that, to the extent applicable, Grants be exempt from or comply with the requirements of Code section 409A. Notwithstanding the foregoing, the Committee makes no representation that the Grants awarded under the Plan shall be exempt from or comply with Code section 409A and makes no undertaking to preclude Code section 409A from applying to Grants awarded under the Plan. To the extent that any legal requirement of section 16 of the Exchange Act or Code sections 422, 162(m) or 409A as set forth in the Plan ceases to be required under section 16 of the Exchange Act or Code sections 422, 162(m) or 409A, that Plan provision shall cease to apply. To the extent applicable, if on the date of a Grantee’s “separation from service” (as such term is defined under Code section 409A), Shares (or shares of any other company required to be aggregated with the Company for purposes of Code section 409A and its corresponding regulations) are publicly-traded on an established securities market or otherwise and the Grantee is a “specified employee” (as such term is defined in Code section 409A(a)(2)(B)(i) and its corresponding regulations) as determined by the Committee (or its delegate) in its discretion in accordance with the requirements of Code sections 409A and 416, then all Grants that are deemed to be deferred compensation subject to the requirements of Code section 409A and payable within six months following such Grantee’s “separation from service” shall be postponed for a period of six months following the Grantee’s “separation from service” with the Company. The Compensation Committee may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government regulation. The Committee may, in its sole discretion, agree to limit its authority under this Section

(g)Grants made in Connection with Corporate Transactions and Otherwise. Nothing contained in the Plan shall be construed to (i) limit the right of the Compensation Committee to make Grants under the Plan in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees, or (ii) limit the right of the Company to grant stock options or make other awards outside of the Plan. The Compensation Committee may make a Grant to an employee of another corporation who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation involving the Company, in substitution for awards made by such corporation. Notwithstanding anything in the Plan to the contrary, the Compensation Committee may establish such terms and conditions of the new Grants as it deems appropriate, including setting the Exercise Price of Options at a price necessary to retain for the Grantee the same economic value as the prior options.

(h)Application of Company Clawback Policy. All Grants under the Plan are subject to the applicable provisions of the Company’s clawback or recoupment policy approved by the Board, or the Compensation Committee; as such policy may be in effect from time to time.

Section 18.Amendment or Termination.

(a)Amendment. The Board may amend or terminate the Plan at any time; provided, however, that the Board shall not amend the Plan without stockholder approval if such approval is required in order to comply with the Code or other applicable law, or to comply with applicable stock exchange requirements.

(b)No Repricing Without Stockholder Approval. Notwithstanding anything in the Plan to the contrary, the Compensation Committee may not reprice Options or SARs, nor may the Board amend the Plan to permit repricing of Options or SARs, unless the stockholders of the Company provide prior approval for such repricing. The term “repricing” shall have the meaning given that term in accordance with the applicable stock exchange in which such shares of Company Stock are registered, as in effect from time to time; provided that an adjustment to an Option or SAR pursuant to Section 13 above shall not constitute a repricing of the Option or SAR.

(c)Stockholder Re-Approval Requirement. If Stock Awards, Stock Units, Other Stock-Based Awards or Dividend Equivalents are granted as “qualified performance-based compensation” under Section 11 above, the Plan must be reapproved by the stockholders no later than the first stockholders meeting that occurs in the fifth year following the year in which the stockholders previously approved the provisions of Section 11, if required by Code section 162(m) or the regulations thereunder.

(d)Termination of Plan. The Plan shall terminate on December 8, 2018, unless the Plan is terminated earlier by the Board or is extended by the Board with the approval of the stockholders.

(e)Termination and Amendment of Outstanding Grants. A termination or amendment of the Plan that occurs after a Grant is made shall not materially impair the rights of a Grantee unless the Grantee consents or unless the Compensation Committee acts under Section 17(f) above. The termination of the Plan shall not impair the power and authority of the Compensation Committee with respect to an outstanding Grant. Whether or not the Plan has terminated, an outstanding Grant may be terminated or amended under Section 17(f) above or may be amended by agreement of the Company and the Grantee consistent with the Plan.
